Meet Our Varicose Vein Treatment Team

Up to 60% of all Americans suffer from a vein disorder such as spider veins or varicose veins.

The cause of spider veins is uncertain, but include factors that weaken vein valves include aging, obesity, leg injury, and prolonged standing. Spider veins on the face of a fair-skinned person can occur from exposure to the sun.

Varicose veins often cause discomfort and look unattractive. Left untreated, varicose veins usually enlarge and worsen over time. They can cause the legs and feet to swell. Leg muscles may feel fatigued or throb and cramp at night. The skin at or around the spider veins or varicose veins can itch or burn, and can occasionally lead to more serious problems.

VEININNOVATIONS is an organization formed exclusively to meet the treatment needs of patients with venous disease. Our center provides state-of-the-art technology ranging from laser vein removal to endovascular closure techniques. Our physicians are Board-certified and have many years of experience.

Read a brief biography of our VI physicians below:

David A. Martin, RNPresident, CEO

David Martin, RN received his degree in Nursing in 1980, and since then has worked primarily in the field of cardiovascular medicine. After 10 years in Intensive Care Units and emergency rooms, he became board certified as a Registered Nurse First Assistant, and went to work with heart and chest surgeons as a first assistant both in the operating room and on the wards. One of his responsibilities was the harvesting of saphenous veins for use as conduit in coronary bypass surgery, and in 1994, he became the first in the State of GA to do this using a scope rather than the traditional open incision method. This method has become the standard of care in GA and is now used in virtually every operating room in the country.

This has such an overall positive impact on peoples lives. It is very gratifying.”
